US gun support runs far deeper than politics

BRYAN, Texas 
Adam Lanza's mother was among the tens of millions of U.S. gun owners. She legally had a .223-caliber Bushmaster rifle and a pair of handguns, which her 20-year-old son used to kill 20 children and six adults in 10 minutes inside a Connecticut school.

In the raw aftermath of the second-worst school shooting in U.S. history, countless gun enthusiasts much like Lanza's mother complicate a gun-owning narrative that critics, sometimes simplistically, put at the feet of a powerful lobby and caricatured zealots. More civilians are armed in the U.S. than anywhere else in the world, with Yemen coming in a distant second, according to the independent Small Arms Survey in Geneva.

Take Blake Smith, a mechanical engineer who lives near Houston and uses an AR-15 style rifle in shooting competitions.

Texas Gov. Rick Perry, who famously claimed to have shot a coyote while jogging with a pistol holstered to his running shorts, has signed a half-dozen certificates applauding Smith as one of the state's top marksmen. "But I won't call myself a fanatic," said Smith, 54, whose father first let him handle a gun around age 6.

"I sit at a desk all day. And when I get out to the range, I don't hear any gunfire going on," said Smith, who likens his emotional detachment to his guns to the way he would feel about a car or any other machine. "I'm so intent on my sight alignment, my trigger pull, my position. I don't worry about anything. I don't think about anything. It's relieving. It's therapeutic. Everybody has to have their Zen."

Since the school shooting, President Barack Obama has asked for proposals on reducing gun violence that he can take to Congress in January, and he called on the National Rifle Association, the country's most powerful gun-rights organization, to join the effort.

Gun laws in the U.S. vary from state to state - for instance, as of last month it is now legal to carry a gun in public view in Oklahoma - and are defended by the firearms industry and the NRA. On Friday, the NRA broke a weeklong silence since the Connecticut massacre by calling for armed volunteers at public schools, prompting criticism from many quarters.

But in the U.S., gun-control advocates are up against a sizeable bloc of mainstream Americans for whom guns are central to their lives, whether for patriotism or personal sense of safety, or simply to occupy their spare time.

Dave Burdett, who owns an outdoors and adventure shop across the street from the sprawling Texas A&M University campus in College Station, says his affinity for guns is rooted in history, not sport.

"It isn't about hunting. Everyone says, `Well, I can understand having a sporting rifle, but not an AR-15," Burdett said. "But wait a second - the idea of the Second Amendment was to preserve and protect the rights of individuals to have those guns."

"Remember that the (American) revolution was fought by citizen soldiers," he added. "To this day, that's one of the cornerstones of our military defense. We have an all-volunteer military."
